OPEN-SOURCE SCRIPT
Exponential weighted volatility
Estimator of current annualized volatility that works for daily, weekly, monthly timeframes.
Lambda should be choosen inside the 0 to 1 range, with a lower lambda giving more weight to the movement in the most recent candlesticks. The literature default is 0.97, I'm setting a default value of 0.94 instead.
